Sample Answer 2
I came down with the Coronavirus during the first few weeks of lockdown and it was a pretty terrifying experience. Not only was it a completely unknown disease, but due to the travelling restrictions and isolation period imposed on those affected, I was not able to have anyone help me or take care of me at all. It began like a cold, only my ears were plugged and I coughed my lungs out. I would get a fever and chills, which became worse at night. I was exhausted – if I took a hot shower to relieve the chills, I’d then have to sit down for fifteen minutes due to my legs trembling before I could do anything else. For the first three days, I had headaches, a sore throat, and lost my sense of smell.
Then for an entire week, I could hardly move. I also lost my appetite, suffered chronic exhaustion, chest and sinus congestion, and developed a fever. I would sleep for most of the day, just getting up to sip water and use the restroom. I was ultimately released from quarantine after three weeks, but I was still suffering from brain fog, just a complete inability to concentrate on things, and it took me a long time to get back on my feet. The strangest aspect was that the symptoms were not consistent. It would be pretty bad one day, then I’d feel mostly normal the next, and then it’d return with a surprising new symptom. It is an unusual sickness with no prediction. I would never wish it on anyone. I’m relieved to finally get the vaccination.
